    Abstract: Techniques and architecture are disclosed for mobile transport systems configured to determine vehicle positions within an area using light-based communication signals. The system includes a plurality of luminaires located in an area and configured to transmit luminaire position data recognizable by a sensor disposed on a vehicle. The sensor receives an image of a luminaire including a light-based communication signal encoded with luminaire position data. Luminaire position data can be combined with luminaire layout information to determine a known location of the luminaire. A vehicle position relative to the known luminaire location can be determined based on mathematical relationships. Vehicle orientation relative to the area can be determined based an asymmetric fiducial pattern or multiple known luminaire locations. The system can combine a vehicle position relative to a known luminaire location with vehicle orientation relative to the area to determine a vehicle position relative to the area.

    Abstract: Techniques are disclosed for augmenting global positioning system (GPS)-based navigation via light-based communication (LCom). In accordance with some embodiments, a light-sensing device, such as a camera or an ambient light sensor configured as described herein, may be used to detect an LCom signal transmitted by a local LCom-enabled solid-state luminaire. The LCom signal may include data about the location of the transmitting luminaire, and in some cases that location data may be used, for example, in computing the amount of time that it would take to navigate indoors to the luminaire's location. In some instances, GPS data also may be considered to calculate the total trip duration for an entire trip, including time spent indoors and outdoors. In some other cases, the location data and, if available, GPS data may be used, for example, in computing an automotive navigation route.

    Abstract: Techniques are disclosed for programming a luminaire with location information, referred to herein as commissioning. Location information may include relative location information (e.g., the position of the luminaire relative to a reference point) and/or absolute location information (e.g., global coordinates for the luminaire). A commissioned luminaire can be configured to emit its location information via light-based communication (LCom). In some cases, the luminaire can be commissioned manually, by hard coding the luminaire with its location either at the luminaire itself or using a device (e.g., a smartphone, tablet, or a dedicated luminaire commissioning device) to program the luminaire with location information. In some cases, the luminaire can be commissioned automatically. In some cases, the luminaire may be configured to provide visual, aural, or tactile feedback to indicate that the luminaire has not received location data or that the luminaire has been moved.
